UPDATE February 27, 2020 - The Molson Coors Brewery campus in Milwaukee will remain closed today after a gunman shot and killed five employees before killing himself Wednesday.

More than a thousand people were at work in what's known locally as Miller Valley, a more than 20 building campus when the shooting began just after 2:00 p.m. at building 4.

The company is not identifying the 51-year-old shooter, but confirms he was an active employee.

Molson Coors CEO Gavin Hattersley says the brewery will be shut down to give workers time to cope with the trauma of the shooting and loss of co-workers.

The Milwaukee Journal Sentinel reports the gunman had two handguns, one with a silencer.

In a late night press conference Wednesday, Milwaukee police say the names of the victims will not be released for 24-48 hours. Investigators are still working to confirm a motive for the killings.

Police say the shooting happened near 41st and State west of downtown.

WISN Radio News reported earlier that Froedtert Hospital had no victims from the shooting.

The shooter is identified by witnesses as an employee in uniform who may have been fired Wednesday.
